Fossil Butte National Monument is near the geographical
center of Fossil Basin. The basin itself is located in the extreme
southwestern part of Wyoming in Uinta and Lincoln counties, near the
Utah-Idaho border (Fig. 2).

The monument is situated about 10 miles west of
Kemmerer, Lincoln County, Wyoming (Fig. 3). U.S. Highway 30N runs just
south of the monument as does the Union Pacific Railroad line to Oregon.
The abandoned town of Fossil is also immediately south of the
monument.
